The guy with the reindeer antlers was the attendant at the desk. She had already thrown a terminal at him before this video started. The real question should be why it took so long for the police to show up. This is an airport. There are cops and security all over the place. They are supposed to be vigilant here. Where were they?
They were probably taking a "union" break.
Guy with antlers should’ve bent at the waist and charged her with his sparkling antlers
